Alas, when the Kyuranger actors and actress finally revealed, we got only positive five cast that have human form. This mean the other four rangers will be played with mask, as they are not human form. To make it clear, here the details story line for Kyuranger as posted in official TV-ASAHI website:
The stage of the story is the far space of the future far away. It is the world where hope was lost under the rule of evil organization Jack Matter.

Actor 岸 洋佑 Kisi Yousuke with his tweet on his character in Kyuranger :
Lastly, actor 山崎大輝 Yamazaki Taiki is second cast to have quite large career information. His official blog in http://ameblo.jp/yamazaki-taiki/ got information to dig in.『ご報告』— 岸 洋佑 (@YosukeYou) December 25, 2016
So, that's all for now. The four remaining alien-type ranger still do not have their voice actor reveals. It is understandable that TOEI will not want to cast as huge as nine actors to bound with their super sentai franchise. This is perhaps to prevent trouble in the future where Kyuranger need to do reunion or a cameo in distance future.
One thing for sure is, Kyuranger going to be a strong series. Here the quotation from producer :
Producer Asahi's Inoue Chihiro producer said, "I just wanted an impact, I did not add up, because one of them needed a number of heroes to deal with the mighty enemies that put the whole space in their hands in the hands." And explained. "Another reason is that I wanted to draw a diverse character so that I could enjoy it throughout the year," he continued. It is said that the width of the story spreads out with a combination of different characters every week.
It is also revealed that the whole Kyuranger character was design by Area 51 artist Masato Hisa.
